CHARLES G. LOHMAIT, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE EDWIN F.G'UTH COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OFMISSOURI.

CANOPY LIGHTING FIXTURE.

Application filed July 15,

My invention relates to the art of illumination, particularly thatportion of'the art wherein mechanical elements are co-ordinated in alighting fixture unit, to intercept, modify and redirect, the rays oflight issuing from the source, so as to be delivered to a working planein a certain desirable manner.

The object of my invention is to provide a lighting. fixture unit toenclose the light source which, when the parts are assembled, willeffectually conceal all securing means and will contain no exposedscrews, bolts or any similar elements which will detract from thegeneral appearance of the unit.

A further object is to provide in a lighting unit a reflector andreflector flange, comprised of one piece, preferably of metal, so formedas to provide co-operating means by which it may be secured to theoutlet box, and also will provide means for holding the bowl or globewhich is designed to surround the lamp.

A further object is to provide such a reflector flange as will alsoprovide means for seating .of the socket.

A further and most important object is to provide such a reflectorflange which,

when made of metal, will be of one piece which may be stamped, therebyproviding simplicity of construction and a material reduction in theordinary expense that would be attendant upon the manufacture of such adevice.

A yet further object is to provide such a reflector flange which willhave a double spaced, wall at its lower portion of said wallsfunctioning for the mounting and stabilizing of securing means for thebowl.

A yet further object is to provide in a lighting fixture of the classdescribed, securing means for the bowl, comprising two stationary lugsand a movable lug held on spring tension, and of a cam construction,which will make it adaptable to bowls of varying sizes.

My invention consists of certain details of construction in which Fig. 1is a vertical sectional view, a portion of the globe being shown inelevation;

Figure 2 is a cross section on line 22 of Fig. 1, with the shade leftoff.

Fig. 3 is a fragmentary detail view of a modified form of fasteningmeans.

Referring to the accompanying drawings, my reflector flange comprises aone piece 1925. Serial No. 43,734.

structure with the horizontal inner section 10 formed to function as areflector, with sides 11 depending therefrom, and thence turningupwardly, as shown at 12, and flaring outwardly to form the canopy whichterminates in the ring '13. In the center of the reflector plate is anorifice 14 designed to receive the mating parts 15 and 16 of a separablesocket, the part 15 having the neck 17 which extends through the orificein the reflector plate, thus providing means for seating the socket inthe reflector plate, as shown. The reflector plate is alsovprovided withorifices 18 designed to receive screws 19 which engage screw threadedorifices in a saddle 20 secured as shown, to the outlet box.

From the construction, as shown and de scribed, it is obvious that thewalls 11 and 12 are spaced from each other, as shown in the sectionalview, and the lugs 21 extend inwardly from the inner wall, formingholding means for the globe 22. There are a plurality of these lugsformed in the manner described, and in one place in this double,

spaced wall, I have provided registering orifices 23 and 24 to receivethe cam-shaped lever 25 which is secured to the reflector flange throughthe medium of an upwardly extending shaft 26 mounted, rotatably, in themetal strap 27, the shaft being held on tension by the coil spring 28,mounted as shown.

The cam-shaped lever terminates, outwardly, in a convenient end formoving it, and the cam shaft 26, rotatably, the tension of the springtending to force the outwardly extending end of the cam lever inwardly.

When my device is formed of metal, the lugs 21 and the variousorificeshereinbefore described are all formed during the stamping, so that myreflector flange is formed at a minimum of expense.

In practical operation, the horizontal part 10 functions as a reflectingmedium for all of the light rays which impinge thereon, and redirectthem downwardly through the globe 22 to the working plane. The globe 22is preferably formed of translucent glass. Globes varying slightly intheir neck size may be mounted to my reflector flange as the cam-shapedlever will account for a limited adjustment. Also, the weight of theglass of the globe is not on the spring 28 but is on the eccentric clipwhich passes through the orifices or slots 23 and 24: and on the lugs21.

Instead of forming the lugs 21 by perforating the inner wall 11 andpushing the cut portion downwardly to. form the lug, registeringscrew-threaded orifices may be provided in the sides 11 and I2 and globesecuring screws secured therein, the double walls 11 and 12 formingmeans to hold each screw rigidly in its horizontal position. This meansof securing the globe is illustrated in the modified form, the screwsbeing designated by the numeral 29. When these screws are used, it wouldbe unnecessary to employ the cam-shaped lever, the cam shaft, themounting therefor and the coil spring, as the holding screws would eachbe adjustable.

It is obvious from the above description that I have produced a lightingunit wherein the canopy, reflector, globe securing means, socketsecuring means and means to secure the canopy to the outlet box are allcombined in one piece and extremely simple, and that the functioning ofthe reflector plate will operate to redirect the upwardly extending raysto the working plane.

Having thus described by invention what I claim and desire to secure byLetters Patent of the United States is:

1. A canopy reflector for lighting fixtures, formed of one piece ofmetal stamped to provide a central horizontal portion to function as areflector and an inner and Outer spaced wall depending below thereflecting portion, said reflecting portion having an orifice centrallylocated therein to receive a lamp socket, and means associated with thecanopy reflector to secure it to an outlet box,

lawyer;

and means in the depending Walls to secure a lighting globe.

2. In a combination canopy and reflector provided with spaced wallsdepending from the reflector, which walls connect the reflector to thecanopy, a plurality of lugs formed on the inner wall thereof, and aspring actuated cam-shaped lug mounted between the said walls, all ofsaid lugs being adapted to receive and hold in place a lighting globe.

3. A combination canopy, reflector, and globe holding means, comprisinga stamping formed of one piece of metal to provide a reflector element,a wall depending below the reflector element, a second wall spaced fromthe first wall, lugs formed on the de pending wall, a spring actuatedlug mounted between the depending wall and its companion spaced wall,all of the lugs being designed to engage a globe and secure it inposition on the canopy reflector, and means to secure the canopyreflector to an outlet box.

4. A combination canopy, reflector, and globe holding means, comprisinga stamping formed of one piece of metal to provide a reflector element,a wall depending below the reflector element, a second wall spaced fromthe first wall, lugs formed on the depending wall, a spring actuatedlug, camshaped-in formation, mounted between the p depending wall andits companion spaced wall, all of the lugs being designed to engage aglobe and secure it in position on the canopy reflector, and means tosecure the canopy reflector to an outlet box.
